every site you have ever visited tracks your browser, IP, OS, location, and more.
This is wrong to a degree of paranoia. That’s simply not true. Every site can observe it, some might even log it, but that’s a far cry for tracking it.
In most cases it’s security by obscurity from sheer numbers that hackers/sites don’t give a crap about you alone.
Also no, maybe in the 90s, but modern systems are (increasingly) designed to be secure by default.
